I am 67 years old and recently diagnosed as Stage 3B. My Internist/nephrologist in Iowa always told me my GFR and Creatinine abnormal chemistries were “just my normal”. I drove to Mayo (5 hours) for a surgical consult for a GI issue back in March 2020. After my visit my internist asked me what Mayo said about my kidneys. I was in shock that he was now asking me this as I had been his patient for the entire 15 years of my altered GFR and Creatinine. Getting nervous I immediately set an appointment with a nephrologist at the University of Iowa. I also found another internist. The U of I nephrologist told me the news of Stage 3B and ordered an ultrasound which found a sizable cyst on one side and a good size stone in the other. I was basically told we will watch things and nothing else. No information about diet or anything else was provided. I have found these different web sites and have pieced together that I should be limiting my sodium to <1500mg/day and protein to <65g/day based on my weight. I have I had a blood test a month ago and my eGFR was 38 and creatinine was 1.79. I had another blood test Monday which showed eGFR 37 and creatinine 1.83. I have been following the diet for 2 weeks. I am more than disappointed. A month ago based on my labs and a 24 hour urine I was put on 10MEQ potassium citrate, Atorvastatin. I was previously on Pantoprazole for my GI issues and Amlodipine for hypertension. My question is does anyone feel it would benefit me to come to Mayo for another opinion. Any help is appreciated.
